I have a strange problem here. I juist bought the P9X79 Deluxe MB along with the 3930k CPU and the H100 to keep things nice and cool. The problem is, my temps at idle are in the 50's so forget about overclocking. This is in a CM HAF 922 case. The case is too small for the fans and the cooler to be inside so I have the fans on the outside pushing air into the case as opposed to pulling air out from the inside. I checked the seating of the block and all seems well but it was very late last night and I may have missed something. I will recheck it and if necessary, re-seat the block...

Does anyone else have this problem???? It seems very strange and either something was missed or the H100 is defective. I know that it's most likely a user error but I'm really trying to figure out why this thing is idling so high. I connected the three pin (which is actually a single pin connection on a three pin adapter) connector to the CPU Fan header and the Molex connectore to the PSU. The three lights on the block light up. I;ve read that I should be hearing a faint sloshing or gurgling noise but I don't hear anything so I'm not sure if I just got a bad cooler or what.

I'm at work right now but I'll try your test. The fans work on all three speed settings so like erocker said, I'll try reseating the block. Is there any way I can be sure that the cooler has the right amount of coolant?

Well it was tge pump afterall and wouldn't you know it, Corsair has been getting A LOT of warranty returns with this sucker. Instead if RMAing it i returned it to the retailer and all is good now. @ 4.5Ghz it now idles between 40 and 50.

I also noticed that the biggest heater maker is the vcore setting. When I bring it down the temps go right down so now im at a point where I'm playing with auto tuning and adjusting the vcore afterwards.

Yeah, there has been a bad batch or something, for sure. Glad you got it sorted so easily, as i did see on the COrsair blog a mentino of this...or maybe it was Guru3d...anyway, the blog had those instrustions I posted in it, and the same idea, that some pumps were bad. The "RESET" was supposed to fix that for some units.

Your idle temps still seem a bit high. What are your ambient temps? My h80 keeps my 2700 idle at low to mid 30's and I'm pumping a hair over 1.4 volts to it. Do you have speedstep enabled? That will bring down temps quite a bit and won't have your cpu running at your oc clocks at idle.

I had a similair issue when I first installed my h80 and was pulling my hair out trying to figure it out. I did some reading and found someone that suggested rotating the block 90 degrees and that somehow gave me better contact and lowered my temps quite a bit. Id suggest trying that if you have not already.

Update: check out the CorsairGeorge's posts in this thread, link at the beginning of this post. The cause has been confirmed to be a shaft/bearing issue which results in rattle under certain circumstances (which I will humbly mention that I have suggested some months ago here), one of them being the voltage to speed correlation, and that is why the diode adapter works - because it slows the pump and puts it out of that resonance/rattle RPM range.

Should it really be that much higher though? He's also got twice the Rad surface compared to me.

I've also got my fan setting on max, with all three lights on the pump and the fans only spin up to max when I get a decent load on the cpu. They don't spin on max 24/7. It gets pretty loud when they do.

yes its that much hotter just ask Dave, he complained that water was neccesary as even his Noctua cooler was getting pretty damn warm when he was testing the chips get HOT lol completely different in terms of heat output compared to 2600k etc.

What Crazy said. For me, power consumption on X79 and SB-E is near double that of P67/Z68 and SB(exactly, in fact. For me, SB @ 4.5 GHz(2600K), 125 W, while SB-E(3960X) @ 4.5 GHZ, 250 W). You can read any release review on SB-E chips to see the same thing reported. That said, I still find X79 faster for my uses, so that's what I use.

I can say that I bought mine fairly recently, and specifically for X79 after talking to a few people that had chips about power consumption. I already had H50 and H70.

Anyway, my unit works just fine, so while thats' interesting info, it must be fixed by now, or I miracuosly got a unit with no problems? But perhaps I could get better performance? I wonder if they have pinned the problem down to a specifci batch...because I am defintiely pushing more than 12 V into mine, and I don't have any issues at all it seems. I haz confuse....

I think it was FullinFusion that pointed out the RESET thing to me, I'm not exactly sure at this point. Too much hardware to play with, I'm losing track of it all.
